Thought you might be interested in this. My 1078RR has a 85 mm vertical crack in the catalytic converter. The bike is still under warranty and I have notified the shop and am just waiting to hear back from them about what they will do to fix the problem. It has sounded wrong for a while now and I just thought it was getting out of tune then I discovered the crack on the weekend which I think explains the strange exhaust note and rough running/backfiring.
